According to the technical personnel of Shimeiji, the newly-developed NBB390/8 mud pump is a mud pump for deep core drilling rigs. It is mainly used for coal geology, metallurgy geology, and hydrogeological engineering exploration within 2,500 meters, and supplies it to the hole. For flushing fluids, it can also be used for other projects. Infusion pump. The mud pump can also change the flow through the replacement of cylinder liners to meet the needs of different drilling depths and provide a new type of supporting equipment for geological exploration.
It is understood that the company has nearly 60 years of history in the development and production of geological exploration machinery. The drilling rig products have been brand-name products in Hebei Province for many years and have won the title of National Customer Satisfaction Products. The products cover geology, petroleum, and water source exploration, etc. The complete range of pumps and rigs, the domestic market share of complete sets of products ranked first, and many exports. This year, the supply of drilling machinery from Shimeiji Machinery Co., Ltd. is in short supply, especially mud pump products are favored by users. The production and sales volume from January to April increased by 69% compared with the same period of last year.
Motocycle battery mainly used for various specifiction of motocycle staring and light, usually motocycle battery is also called motocycle starting battery.
Electric motorcycle battery is the small heart of electric motorcycle. Its safety, environmental protection and durability are the most important performance for consumers. Currently motorcycle battery already renovate the traditional process of lead-acid batteries and establish a new green environmental protection and energy-saving process. Because the traditional chemical conversion process is cut off and the main pollution is eliminated, the product is environmentally friendly; the quality is high, the service life is long, the capacity is large; the low temperature start performance is good, and it is especially suitable for use in cold regions in the north. As a power battery, it can be discharged at a high rate; it has a small self-discharge and is suitable for long-term storage; it has obvious cost performance advantages compared with other imported batteries.
Motorcycle battery use and maintenance According to the technical conditions of the battery, the correct charging voltage of the motorcycle battery should be maintained at 13V-16V, and the charging current should be 0.1A-2.5A. Some motorcycle manufacturers have set the clamp voltage of 15V, which is more suitable and can be used for reference. But there are many motorcycle manufacturers lack of knowledge in this respect, the charging system is not strictly controlled, resulting in no regulation of the charging voltage, current, with the increase of engine speed and increase, high speed can reach 18V4A above, so that the rapid evaporation of battery electrolyte affect its performance, especially for maintenance-free battery, because of the rapid evaporation of electrolyte and shorten its life; Some motorcycles charging voltage is very low, only 13V or lower, so that the battery long-term charging insufficient failure, consumers do not know the reason, only constantly replace the battery. For these cases, consumers should check the charging system in time, replace the rectifier regulator, motorcycle electrical parts manufacturers should fully grasp this knowledge, produce products that meet the technical requirements. The main electrical components which have direct influence on the use of battery are: rectifier regulator, electric door lock, starting relay, anti-theft device and so on. In order to pursue low cost and low price, some enterprises produce electrical components that do not meet the requirements at all. For example, the electric door lock cannot completely cut off the circuit when it is closed, the rated current of the immobile device is greater than 5mA when it is in standby state, and the rectifier regulator only has the function of rectifier without regulating voltage and current. Consumers should carefully judge and buy electrical components of good quality that meet the requirements. One, usually how to maintain the battery.
1. How to maintain the battery in use the battery should be regularly checked the liquid level of the electrolyte, so that it is located in the specified range. If the electrolyte splash, pour and cause the liquid level to drop, it should be added a certain proportion of electrolyte. If it is because the distilled water is evaporated and the liquid level drops, then the distilled water should be added. For the normal use of batteries to add the main should be distilled water, because sulfuric acid is almost not consumed. The filling plug should be covered in time after charging and filling; The surface of the battery should be kept clean to prevent debris from entering the battery and causing short circuit and self-discharge between the electrodes. The battery shell should be maintained to avoid breakage. Electrolyte leakage is found, should be cleaned in time to prevent the surrounding parts by acid corrosion. Positive and negative terminals have good electrical conductivity. If the surface is oxidized or corroded, it should be cleaned in time and coated with butter.
Three, how to safely use battery plus electrolyte to use protective equipment, beware of electrolyte overflow or splash on the skin. The remaining electrolyte should be kept in a container and neutralized with quicklime when discarded. Before charging, the filling plug should be opened, because the battery should release a lot of gas when charging. In addition, pay attention to good ventilation in the charging room, and smoking should be strictly prohibited.
Dispose the waste battery in time to prevent the electrolyte from flowing out and damaging the surrounding objects. Not to be played with by children. When the electrolyte touches the skin, wash with clean water immediately; If splashing into eyes, rinse immediately with water for 15 minutes. The electrolyte is mistakenly eaten into the body, immediately drink water for several mouthfuls, and then the egg white and emulsion mixed drink; You can drink a lot of water and rest. When the electrolyte is splashed on the clothes, wash them with water immediately and then neutralize them in a weakly salty solution.
